Disapointed with the PC

Disapointed with the PC

I bought the PC (liked it), bought the #80 (tried this first) and the #83 (tried this second) and those darn scratches just won't budge. I have to say that I'm a bit disapointed but I guess those scratches are just to deep. I am inclined to keep trying but I don't want to ruin the paint...any suggestions?

Hi:

When you slide your finger nail over the scratch can you feel it?

Maybe it's technique, are you polishing a 12" x 12" space? Are you using one product per pad? Here look at this:

Those scratches look like they would come out easily to me...

It's all in your technique

Work a small area at a time, about 12 to 16 inches squared

Push down on the head of the polisher with about 15 pounds of pressure

Move the polisher slowly over the finish, most people move it to quickly

Overlap your passes by 50%

Work the area until the product almost disappears but doesn't and you still have a wet film on the surface

If one application doesn't remove the defects, try a second application after wiping off the residue from the first application

My first experience with a DA was much the same as yours, pammer, but after some (literal) hands on instruction from Mike Phillips I discovered that my technique was sorely lacking. There are quite a few variables here - hand speed, machine speed, pressure, aggressiveness of pad & product, working time - and if you don't get them all in sync you tend to just push product around. Once you get everything "aligned" so to speak, it just plain works.

Stick with it. Odds are, if you aren't removing those fine scratches you aren't doing any damage at all to the paint.

Try again

I'll give it another go. Those scratches truly bother me and this is such a pretty car I would love it to have a nice scratch free surface.

and yes, some of the scratches catch a fingernail but not all of them.

For the scratches that are deeper, first try rubbing them with ScratchX by hand and put some passion behind the pad. Go across them, (90 degrees or so), and not with them. Apply ScratchX using a microfiber polishing cloth or a peice of terry cloth towel.

You can exert more force with your fingers to a small area than you can with a 6" diameter foam pad oscillating on a dual action polisher.

After working the scratches by hand, then re-polish the area with the dual action polisher.

Last Saturday, at the Porsche class here at Meguiar's we removed isolated scratches by using the Feathersanding Technique, I'm sad to say I have not had the time to upload all of the pictures from the class but the technique is very effective at removing isolated scratches like these.

It was the same way we removed the egg impact scratches from fatchance's Chrysler 300 here,

John aka fatchance, let us do a little wet-sanding on his Chrysler 300 as the hood was hit with an egg and it left some deeper scratches on the hood.




This photo was actually taken after wet-sanding with a backing pad and then using a rotary buffer with a cutting pad and M84 Compound Power Cleaner to remove the sanding marks. We didn't get any pictures of how bad the scratches were before we started but you'll get the idea...




After removing all the lighter scratches from the process above, we then cut up some small pieces of Nikken #2500 grit Finishing Paper to zero in on just the scratches while sanding.






After sanding each of the individual scratches flat, we then removed the sanding marks using the W-7006 Foam Cutting pad with some more M84 Compound Power Cleaner at around 1500 rpm.




We then re-polished the area with a W-8006 Foam Polishing Pad and some M83 Dual Action Cleaner/Polish with the rotary buffer, the re-polished again using M80 Speed Glaze with the G100 and then applied some M21 Synthetic Sealant.

About the only sign of the scratches left was this tiny little residual scratch right here...

When is it appropriate to use M21 Synthetic Sealant? How is it applied?

[F-150]

There are many posts on M21, just search M21 synthetic sealant or just #21 and you'll get a lot of results. Basically to answer you question briefly tho, most use a G100 with a W-9006 foam finishing pad to apply #21. And when is it appropriate? Well if I'm understanding your question right, just make sure to prep the finish first. (using a paint cleaner, clay, etc.)

F-150 has it right, you must first prep the finish first. Then use the M21, and apply it just like wax. M21 is NXT Tech wax for the professional line. It only comes in the 1/2 gallon size, which would take a long time to use up. It's about $55 with tax/shipping.

You can always get a sample from autodetailingsolutions tho.

The best thing to do would be to start your own thread, posting this question in pammer's thread is called taking a thread off-topic.

It's okay if you didn't know you were taking someone else's thread off-topic, or if you didn't know where to post your questions.

When in doubt, post your questions in the Detailing 101 forum here,

(Which is the forum we're in, you just need to start your own thread)

Let us know if you were able to remove the scratches, perhaps a write-up in the Show Off or Extreme Makeovers threads.
